    3.4 Configuring Encoder Format and Bitrates The QVidium H.264 HD Video Codec™ includes a video scalar on the input and can encode all standard broadcast resolutions as either MPEG4-AVC (H.264) or MPEG2. It can scale a high definition (HD) video input to standard definition (SD), or can encode HD video up to 1080p60 (1920x1080 resolution at 60 frames per second, Level A and Level B).

    All advanced IP/Ethernet network settings are located under the Advanced Network tab. Warning: Some combinations of parameters can cause the encoder to malfunction. QVidium does not test, nor can it support, all possible combinations of parameters. Instead, we allow users the flexibility of setting these parameters to suit their needs, and make the decision for themselves as to whether the resulting operation meets the needs of an application.

If the value of the Jitter Buffer is non-zero, the QVidium QVPRO H.264IP Codec will process all incoming video/IP packets through a time-based buffer that removes variations in packet arrival times, also known as packet jitter, and reorders RTP encapsulated packets by their RTP sequence number.
